Long Multiplication Techniques for 11+ Maths: Calm Support for Parents Helping Their Child
19 October 2026
Why long multiplication matters
Long multiplication is a core skill for the 11+ Maths exam. It helps children handle large numbers confidently and builds a strong foundation for more advanced topics. Mastering this method can make many other areas of maths feel much more approachable.
Step-by-step standard method
Start by writing the two numbers you want to multiply, one above the other, aligning the digits on the right. Multiply the top number by each digit of the bottom number, starting from the units. Write each result (partial product) on a new line, shifting it one place to the left each time you move to the next digit. Finally, add all the partial products to find the answer.
Avoiding common mistakes
Encourage your child to check their alignment, especially when adding zeros as placeholders. Remind them to work slowly and double-check each step. Using squared paper can help keep numbers neat and reduce errors.
Alternative approaches
Some children find the grid (or box) method helpful. This breaks the calculation into smaller, more manageable parts, making it easier to follow the place value. If your child is struggling with the standard method, it's fine to use alternatives to build confidence.
Supporting your child calmly
Try to keep practice sessions short and positive. Focus on understanding, not speed. Praise effort and progress, even if mistakes are made. Your encouragement helps your child feel safe to learn and improves their confidence.
Key insight: Practising with real examples, such as working out the cost of several items or doubling a recipe, makes long multiplication feel more meaningful and less abstract.
Encouragement for the journey
Every child learns at their own pace. With patient support and regular practice, long multiplication becomes much less daunting. Remember, your calm guidance makes a real difference.
